Description

TECHNICAL FIELD
This Invention relates to a kind of microfiber artificial leather and its manufacturing methods, more precisely, a kind of suede made taking ultrafine polyester as the major raw material, applying a special three-dimensional weaving process, using a special macromolecule polymer elastomer and adopting the wet leather manufacturing process, as well as corresponding manufacturing methods. It is a kind of textile and leather technology.
BACKGROUND ART
Currently, the microfiber artificial leather produced abroad and at home mostly takes the sea-island superfine fiber as raw materials, experiences the opening, carding and netting process, accepts repeated consolidation on a acupuncture (or spunlace) machine to form a fabric, then has the sea part dissolved (or extracted) by polyurethane padding, coagulation and lye (or solvent) treatment, and finally accepts sanding, dyeing and finishing to make into finished products.
According to different production technologies, the sea-island superfine fiber can be divided into volatile sea-island superfine fiber (volatile island microfiber) and fixed sea-island microfiber (fixed island microfiber). The island in volatile sea-island microfiber is not controllable, featuring non-continuity on the vertical axis, and can be made into microfiber featuring irregular thickness and length through solvent treatment; however, the fixed sea-island microfiber is continuous on the vertical axis, and a kind of symmetrical microfiber featuring a fixed number of islands, as well as consistent fiber and uniform length. The number of islands in fixed sea-island microfiber generally includes such specifications as 16 islands, 24 islands, 37 islands and 64 islands, with 37 islands in common use.
For the nylon microfiber artificial leather featuring volatile island, its volatile island microfiber is usually blended with polyamide and polyethylene or other soluble macromolecule polymer materials at a certain percentage based on the threading process, after the artificial leather fabric is fabricated, and then toluene is used to dissolve polyethylene for fiber opening followed by post-processing. The products based on this process have the fiber monofilament size up to 0.0001 dtex (for fine ones) and 0.1 dtex above (for thick ones). The larger discreteness of size may have certain effect on post-processing and product quality; and, in the process of production, the toxic solvent toluene is easy to evaporate, which has great influence on operators' health and environment. Moreover, the characteristics of nylon fiber itself indicates that related products feature poor uniformity, low color fastness, poor abrasion resistance, no dense hair, low density and other defects, so that there should be certain limitations to its applications.
Non-woven fabric is used as artificial leather fabric, and acupuncture (or spunlace) is adopted to have the fibers tangled together, but this entanglement has its instability, (and some manufacturers add a layer of woven fabric between non-woven fabrics to increase the stability of the product). Embedded with polyurethane resin, but the fiber is relatively easy to fall off from the product, that is, it features poor wear resistance. This process can not form enough three-dimensional fibers with sparse hair on the surface so that the products feel rough and can not meet requirements for use in some areas.
INVENTION DETAILS
In order to overcome the defects of artificial leather based on existing technology, such as no enough three-dimensional fiber, no dense hair on the surface, rough feeling and inability of meeting the use requirements in some fields, this Invention provides a manufacturing method for microfiber artificial leather, including the steps as follows:
(1) Microfiber (such as a microfiber dyed before spinning) is select as pile warp, with the filament or yarn (such as a yarn dyed before spinning) taken as ground warp and ground weft. The pile warp adopts V-shaped or W-shaped consolidation, uses the double warp-pile weaving technology to weave into double-layer pile fabric on pile weavers, and adopts pile cutters to cut the pile warp thread joining the two layers of the ground fabric so that the double-layer pile fabric could be halved into single-layer pile fabric respectively with ground warp, ground weft and V-shaped or W-shaped pile warp, featuring a three-dimensional structure;
(2) The pile fabric is immersed into polyurethane finishing liquid, padded, then treated in a coagulating liquid, washed and dried, so that the polyurethane in the pile fabric could form sponge-like continuous microporous membrane;
(3) After dried, the microporous membrane pile fabric with polyurethane contained is applied with alkali treatment, so that the pile warp could fully be dispersed into single fibers to form microfibers, and then fully washed in water to remove alkali liquid, as well as alkali-soluble monomers and oligomers;
(4) Carry out sanding, dyeing and finishing operations to obtain microfiber artificial leather.

The pile warp (1) adopts V-shaped (as shown in FIG. 2 or FIG. 3) or W-shaped (as shown in FIG. 4) consolidation, uses the double warp-pile weaving technology to weave into double-layer pile fabric (as shown in FIG. 5) on pile weavers, and adopts pile cutters to cut the pile warp thread joining two layers of ground fabric so that the double-layer pile fabric could be halved into single-layer pile fabric (as shown in FIG. 6) respectively with ground warp (2), ground weft (3) and V-shaped or W-shaped pile warp (1) (which is called as rough surface), featuring a three-dimensional structure;
(2) Immerse the pile fabric with the finishing liquid containing 5%-30% polyurethane resin (preferably 10-20%), DMF, and 0-5% (preferably 1%-3%) anionic and non-ionic surfactant, in which weight ratio of polyurethane finishing liquid and pile fabric is 80%-400% (preferably 100%-200%). Then, the fabric shall be padded, immersed in coagulating liquid, washed in water, squeezed and dried;
Thereinto, the coagulating liquid is a kind of solution prepared by DMF with the weight ratio of 10%-30% (preferably 15%-25%) and water.
(3) Immerse the pile fabric with polyurethane contained after dried into alkaline solution, treat it under the temperature of 95-120 degrees for 10-30 minutes, dissolve the “sea” part in the sea-island polyester, fully disperse the “island” part to obtain the microfiber with the single filament size of 0.55 dtex or below, and then fully wash it in water to remove alkali, as well as alkali-soluble monomers and oligomers.
(4) Carry out sanding, dyeing and finishing, and obtain polyester microfiber artificial leather.
Thereinto, the sanding may have great impact on the plush feeling of the artificial leather hair surface, and this Invention adopts the sandpaper (220-600 meshes) surfaces of different types based on test to carry out several times of sanding treatment (first heavier, and then lighter) and obtain suedette artificial leather featuring standing hair and fine silky feeling.
Dyeing steps: Select high-quality dispersed dyes, such as those dispersed dyes featuring good wash fastness and excellent light fastness, make use of overflow dyeing machine for dyeing, strictly control the dyeing process conditions (130° C., 60 minutes), and strengthen after-dyeing wash to ensure uniform product color, pure shade and good color fastness.
(5) Coat with a layer of sea-island polyester microfiber (4) (as shown in FIG. 6) on the back of the hair-standing surface to further improve its wear resistance; or a layer of water-soluble polyurethane resin on the back of the hair surface to reduce the shedding of hair.
